Many developing countries are closely watching the role escalating food prices is playing in the turmoil in North Africa.

Government repression, corruption, unemployment and poverty united protesters to oust Egyptian President Hosni Mubarak last week. But experts say the rising price of food was one of the sparks that set off the historic protests.

The global price of wheat has risen 60 percent in the past year, and Egypt is the world's largest wheat importer. But that was not always the case.

"I find it actually ironic that bread lines are what provoked the latest political unrest," says policy analyst Marie Brill, with the advocacy group ActionAid, "considering that in the 1960s, Egypt had been a breadbasket (major wheat producer) and able to meet its own wheat needs."

Focus on exports

So what happened? Brill says it goes back to the 1980s and 90s, when the United States, the World Bank and the International Monetary Fund encouraged developing countries to import grain produced cheaply in the U.S. and elsewhere and to focus their farming on export crops.

"This has been a policy that has been pushed around the world, not just in Egypt or in the Middle East," Brill says. "But what we've found was that, as Egypt became more and more dependent on [imported] wheat, Egypt also became more and more vulnerable to price hikes and price volatility."

"That has been used as a crutch by Arab regimes to justify their failures," Eljahmi says. "The problem is, there is a legacy of corruption. There is a lack of accountability. So, the failure really rests with the nature of the military regime in Egypt. Not the IMF or anything."

Subsidized bread

Whatever the cause of the failure, Egypt's food production has not kept pace with its population growth.

As prices climbed in recent months, the Egyptian government had to pay dearly to import wheat for its subsidized bread program. The country was already deeply in debt, which limited how it could respond to the protests.

"So, they really didn't have any scope for doing what an oil-producing country like Algeria could," says senior fellow Mohsin Khan at the Peterson Institute of International Economics. "Which is, you have unrest and you can throw money at it."

Algeria has made huge wheat purchases and set price controls following street protests. Not all citizens have been placated, and some protesters returned to the streets this weekend.

Other countries watching

According to the UN Food and Agriculture Organization, there are 77 low-income countries that rely heavily on food imports.

Khan says policymakers in these countries are going to say, "'Look, we have large-scale unemployment.We have high food prices rising and therefore pushing up inflation. This is likely to trigger protests in our country. So, what do we need to do?'"

Targeted aid, not subsidies

Khan says poor countries need to target help to the poor, rather than blanketing the economy with price controls or food subsidies, which are expensive and bad for the economy in the long run.

But they are among the easiest options. And Khan adds that people in other repressed countries may be inspired by events in Egypt and Tunisia, where food prices also contributed to the ouster of President Zine el-Abidine Ben Ali last month. He says governments will likely be tempted to step in rather than risk protests.

"It's going to be very interesting to see how it plays out in terms of who's going to [act] first," he says. "Are the protests going to come first, or [are the governments going to] start subsidizing food?"

Many experts agree the likelihood of protests is rising along with the cost of food.
